Contact the embassy for your spouse's country of residence. The method for serving your spouse with your divorce papers outside of the United States will depend largely on the laws of his country. Treaty laws with your spouse’s country might also apply. The U.S. Department of State is also able to provide you with this information.
Translate the divorce complaint into the native language of the country in which your spouse resides. That country may require a translation even if your spouse speaks and reads English. The country’s embassy or the U.S. Department of State may be able to tell you if you must go through this extra step.
Take your divorce complaint to the post office if your spouse’s country is one that will allow you to serve him by mail. China, Japan, Germany, Poland, Argentina, Venezuela and Switzerland are among many countries that do not. If the country your spouse is living in permits service by mail, send your complaint to him by international registered mail, and complete postal form 2865 for a return receipt.
Contact the court where you filed your complaint if your spouse’s country of residence will not accept service by mail. If that country is a signatory to the Hague Service Convention, the court can request process of service as a “letters rogatory” procedure. The court will forward a copy of your complaint to a process server in that country and work through its government to get your complaint served.
File your mail return receipt with the court to prove that your spouse received your complaint if you were able to serve him by international registered mail. States may use different forms for this. The court clerk can advise you which form you must complete and attach to the international mail receipt. If the court has served your spouse through the "letters rogatory" process, you generally will not be required to do anything more, but check with your court to be sure.
